Abstract The study analyzed the consumption of non-standard medication in the health of indigenous peoples, emphasizing the rationality of pharmacotherapy, by conducting a cross-sectional study of secondary data from 2018 and 2019 in the Minas Gerais/Espírito Santo Special Sanitary Indigenous Health Districts. These medicines were classified by Anatomical Therapeutic Chemical Classification. Non-parametric tests were applied to compare the origin of prescription and the form of acquisition, assessing access to medication. Rationality was verified through the consumption profile and the therapeutic option in the list of standardized medicines. A total of 104,928 pharmaceutical presentations were consumed, 66,967 (66%) for the alimentary tract and metabolism, 17,705 (17%) for the nervous system, and 12,961 (12%) for the cardiovascular system. With respect to medicines consumed per region, 171 (90%) out of 190 had a therapeutic option. Prescriptions were more from the SUS. Differences were found in the way the medicines were acquired. The study pointed to significant consumption of non-standard medicines, and there may be failings in therapeutic rationality. In indigenous health, ethnocultural and social issues are challenges to access to medicines with rational use.

Resumo O estudo analisou o consumo de medicamentos não padronizados na saúde indígena, enfatizando a racionalidade da farmacoterapia, por meio de um estudo transversal dos dados secundários, de 2018 e 2019, no Distrito Especial Sanitário de Saúde Indígena Minas Gerais/Espírito Santo. Esses medicamentos foram classificados pela Anatomical Therapeutic Chemical Classification. Para a comparação da origem de prescrição e da forma de aquisição, empregaram-se testes não paramétricos, avaliando o acesso a medicamentos. Verificou-se a racionalidade por meio do perfil de consumo e da opção terapêutica na lista de medicamentos padronizados. Foram consumidas 104.928 apresentações farmacêuticas, 66.967 (66%) eram para o trato alimentar e o metabolismo; 17.705 (17%) para o sistema nervoso; 12.961 (12%) para o sistema cardiovascular. Quanto aos medicamentos mais consumidos por regiões, 171 (90%) dos 190 apresentavam opção terapêutica. As prescrições foram mais provenientes do SUS. Encontraram-se diferenças na forma de aquisição dos medicamentos. O estudo apontou importante consumo de medicamentos não padronizados, podendo existir falhas na racionalidade terapêutica. Na saúde indígena, questões etnoculturais e sociais constituem desafios para o acesso aos medicamentos com uso racional.

Resumo O presente estudo teve como objetivo realizar uma revisão narrativa de literatura acerca das dificuldades enfrentadas pelas pessoas em situação de rua, durante a pandemia de COVID-19, e teorizá-las a partir das três dimensões de Ayres: vulnerabilidade individual, social e programática. Para tanto, foi feito um levantamento de artigos científicos em diferentes bases de dados - Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Publons, Web of Sciences e portal PubMed -, referente ao período de janeiro de 2020 a julho de 2021, sendo coletados 42 textos. Os achados foram analisados a partir do quadro conceitual da vulnerabilidade, que engloba os comportamentos e características de vida de um grupo específico, sua dinâmica com a sociedade e acesso a recursos públicos, os quais contribuem para maior ou menor exposição a um agravo. Dentre as medidas aplicadas durante a pandemia, o cuidado em saúde mental das pessoas em situação de rua não foi prioridade, com registros de poucos serviços ofertados. Percebe-se como um grupo vulnerável se tornou ainda mais vulnerável e como sua invisibilidade dificultou a criação de respostas mais céleres.

Abstract The present study aimed to conduct a narrative review of the literature about the difficulties faced by people living on the street during the COVID-19 pandemic, and to theorize them based on Ayres' three dimensions: individual, social and programmatic vulnerability. To this end, a survey of scientific articles was made in different databases - Latin American and Caribbean Literature on Health Sciences (LILACS), Publons, Web of Sciences and on the PubMed portal -, referring to the period from 2020 to 2021, 42 texts were collected. The findings were analyzed based on the conceptual framework of vulnerability, which encompasses the behaviors and characteristics of life of a specific group, its dynamics with society and access to public resources, which end contribute to the greater or lesser exposure to an injury. Among the measures applied during the pandemic, mental health care for homeless people was not a priority, with records of few services. It can be seen how a vulnerable group became even more vulnerable, and its invisibility made it difficult to create more productive responses.

Abstract: The objective of this study was to evaluate the quality of milk and cheese and sensory analysis of cheese from goats that received a diet with different levels of sorghum silage in the diet. Twenty Anglonubian dairy goats were used, with an average age of 2 years, average live weight of 43.7 kg, distributed in a completely randomized design, with five replications. Moisture (P=0.001), total solids (P=0.001), fat (p=0.001), TDE (P=0.006) and protein (P=0.003) of goat cheese showed a significant difference due to the inclusion of silage from goat cheese. sorghum in the diet. The sensory attributes soft appearance (P<.0001), look (P<.0001), salty taste (P<.0001) and smooth texture (P=0.0430) showed a significant difference depending on the level of sorghum silage added to the diet. of goats. In the PC analysis, it is observed that three main components were needed to represent the variation of 64.84% of the data. PC 1 determined 29% of the data variation and was represented by the attributes with the highest averages: attractive aroma (5.87) and global acceptability (7.74). The inclusion of up to 45% of sorghum silage in the diet of goats increased milk and cheese fat, which favored high scores for the attributes of softness and global acceptance.

Resumo Objetivou-se analisar a associação entre consumo de bebidas alcoólicas e adiposidade abdominal em adultos. Estudo transversal realizado com dados da linha de base do ELSA-Brasil (2008-2010). A amostra foi constituída por 15.065 servidores públicos de seis instituições de ensino e pesquisa (35 a 74 anos, ambos os sexos). Para identificar adiposidade central por meio das medidas de circunferência da cintura (CC) e relação cintura/quadril (RCQ), utilizou-se os pontos de corte preconizados pela Organização Mundial da Saúde. Para as análises estatísticas foi utilizado o teste qui-quadrado e modelos de regressão de Poisson ajustados por variáveis potencialmente confundidoras. Cerca de 40% da amostra apresentava CC e RCQ elevadas. A probabilidade de apresentar CC elevada foi 5% e 3% maior no grupo mais exposto de consumo de cerveja em homens e mulheres quando comparado ao grupo de referência [RP = 1,05 (IC 95% 1,02-1,08) e RP = 1,03 (IC 95% 1,00-1,07)]. Também foi encontrada maior probabilidade de apresentar RCQ elevada entre os maiores consumidores de cerveja [RP = 1,03 (IC 95% 1,00-1,07) em homens e RP=1,10 (IC 95% 1,04-1,15) em mulheres]. Maior número de doses/semana de bebida alcoólica aumentou a probabilidade de ocorrência de CC e RCQ elevadas, sendo mais importante a contribuição da cerveja.

Abstract The objective was to analyze the association between alcohol consumption and abdominal adiposity in adults. Cross-sectional study conducted at baseline data from ELSA-Brasil (2008- 2010). The sample consisted of 15,065 civil servants from six education and research institutions (35 to 74 years old, both sexes). To identify central adiposity by measuring waist circumference (WC) and waist-to-hip ratio (WHR), the cutoff points recommended by the World Health Organization were used. Poisson regression models adjusted for potentially confounding variables were tested. About 40% of the sample had elevated WC and WHR. The probability of having elevated WC was 5% and 3% higher in the most exposed group of beer consumption in men and women when compared to the reference group [PR= 1.05 (95% CI 1.02-1.08) and P R= 1.03 (95% CI 1.00-1.07)]. A higher probability of having a high WHR was also found among the highest beer consumers [PR = 1.03 (95% CI 1.00-1.07) in men and PR = 1.10 (95% CI 1.04-1.15) in women]. A greater number of doses/week of alcoholic drink increased the probability of occurrence of high WC and WHR, with the beer contribution being more important.

Resumen: En | Texto: En | PDF: En

Abstract Objective: To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process. Methods: A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree. Nineteen questions were addressed and discussed via teleconference to formulate the answers. In order to identify the relevant data on COVID-19 vaccines, a search with standardized descriptors and synonyms was performed on September 10th, 2021, of the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and LILACS to identify studies of interest. We used the Newcastle–Ottawa Scale to assess the quality of nonrandomized studies. Results: All the nineteen questions-answers (Q&A) were approved by the BSR Task Force with more than 80% of panelists voting options 4—agree—and 5—strongly agree—, and a consensus was reached. These Guidelines were focused in SMD on the most appropriate timing for IMRD patients to get vaccinated to reach the adequate covid-19 vaccination response. Conclusion: These guidelines were developed by a BSR Task Force with a high LOA among panelists, based on the literature review of published studies and expert opinion for COVID-19 vaccination in IMRD patients. Noteworthy, in the pandemic period, up to the time of the review and the consensus process for this document, high-quality evidence was scarce. Thus, it is not a substitute for clinical judgment.

ABSTRACT We aimed to determine the prevalence of infection markers in donors of a Peruvian blood bank and to assess whether donor sociodemographic variables are associated with the presence of these markers. An analytical cross-sectional study was carried out in 5942 donors of a blood bank, whose data was collected during 2018. Positivity to human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and HTLV I-II was determined, in addition to syphilis and Chagas disease. The prevalence of HIV was 0.81%; for HBV it was 6.19%; for HCV, 0.12%; for HTLV I-II, 0.66%; for Chagas disease, 2.76% and for syphilis it was 1.73%. Several sociodemographic factors were associated with infection markers positivity. The predominant donation type was non-voluntary (96%) and 53% had history of previous donation. The prevalence of infection markers for HIV, HBV, Chagas disease and syphilis in blood donors was high compared to other countries in the region.

RESUMEN Se buscó determinar la prevalencia de marcadores infecciosos en donantes de un banco de sangre en Perú y valorar si las variables sociodemográficas del donante se asocian con la presencia de estos marcadores. Se realizó un estudio transversal analítico en 5942 donantes de un banco de sangre durante el 2018. Se determinó la positividad a inmunodeficiencia humana (VIH), hepatitis B (VHB), hepatitis C (VHC) y HTLV I-II; además de sífilis y enfermedad de Chagas. La prevalencia de VIH fue 0,81%, VHB 6,19%, VHC 0,12%, HTLV I-II 0,66%, enfermedad de Chagas 2,76% y sífilis 1,73%. Diversos factores sociodemográficos se asociaron con la positividad de marcadores infecciosos. El tipo de donación predominante fue no voluntaria (96%) y el 53% presentó historia de donación previa. Las prevalencias de marcadores infecciosos de VIH, VHB, enfermedad de Chagas y sífilis en los donantes de sangre fueron altas comparadas con otros países de la región.

Resumen: En | Texto: En | PDF: En

ABSTRACT Background: The objective of the present work was to investigate the influence of a pre-treatment of microbial-rich digestate (liquid mesophilic anaerobic digestate - AD-supernatant) on the morphology, crystallinity, and thermal stability of cellulose pulp fiber. Results: The six most abundant bacteria in the AD-supernatant were determined by 16S analysis. The bacteria population was comprised mostly of Bacteroides graminisolvens (66%) and Parabacteroides chartae (28%). Enzymatic activity from the bacteria partially removed the amorphous components and increased the crystallinity and crystallite size of the cellulose substrate. The fiber pulp was incubated in AD-supernatant for 5, 10, and 20 days. The X-ray diffraction data provided evidence that the amorphous portion of the cellulose was more readily and quickly hydrolyzed than the crystalline portion. The longest incubation times (20 days) resulted in substantial deconstruction of the cellulose fiber structure and decreased the thermal degradation temperature. Conclusion: The anaerobic digestate is inexpensive and could be used to effectively aid in the pre-treatment of cellulose on large scale transformation processes, e.g. for making biofuels, cellulose micro/nanofiber production or engineered fiber-based materials.

Resumen: En | Texto: En | PDF: En

ABSTRACT Salvia hispanica L. is an alternative crop cultivated by farmers who want to diversify their production. However, this species is sensitive to salinity, which affects its germination negatively. Seed priming with different attenuators is a technique with potential to mitigate the effects of salt stress. Thus, the objective of this study was to evaluate the effect of seed priming with the use of different attenuators on the germination, growth, and organic solute accumulation of S. hispanica seedlings under salt stress. The experimental design was completely randomized, with treatments distributed in a 4 × 5 factorial scheme, corresponding to four seed priming treatments and five osmotic potentials, with four replicates of 50 seeds in each treatment. The seed treatments consisted of presoaking seeds for 4h in salicylic acid, gibberellic acid, and distilled water and the control treatment, which did not involve soaking. These seeds were germinated at osmotic potentials of 0.0, -0.1, -0.2, -0.3, and -0.4 MPa, using NaCl as an osmotic agent to simulate the different salinity levels. Among all the treatments implemented, S. hispanica seed priming with salicylic acid was the most efficient in mitigating the salt stress effects.

Abstract Objective To evaluate the effect of a toothpaste containing calcium silicate/sodium phosphate/fluoride associated or not to the boost serum (BS) against erosive tooth wear (ETW) on enamel and dentin. Methodology Bovine enamel and dentin specimens were subjected to an erosion-abrasion cycling model (1% citric acid - pH 3.6 -2 min / artificial saliva – 60 min, 4×/day, 5 days). Toothbrushing was performed for 15 s (2 min exposed to slurry), 2×/day, with the toothpastes (n=10): control without fluoride (Weleda), Arg/Ca/MFP (Colgate Pro-Relief), Si/PO4/MFP (Regenerate-Unilever), and Si/PO4/MFP/BS (Si/PO4/MFP with dual BS – Advanced Enamel Serum-Unilever). The effect of treatments on the eroded tissues was assessed by surface microhardness in the first day, and surface loss (SL) resulting from ETW was evaluated by profilometry (μm) after three and five days. Additional dentin specimens (n=5/group) were subjected to 20,000 brushing cycles to verify the abrasivity of the toothpastes. Data were subjected to ANOVA and correlation tests (5%). Results For enamel, no difference in microhardness was observed among the treated groups, and similar SL was obtained after 5 days. For dentin, Si/PO4/MFP/BS resulted in higher microhardness values, but none of the groups presented significantly lower SL than the control. There was no significant correlation between SL and abrasiveness. Conclusion The calcium silicate/sodium phosphate toothpaste and serum increased microhardness of eroded dentin, but they did not significantly reduce enamel and dentin loss compared to the non-fluoride control toothpaste. The abrasiveness of the toothpastes could not predict their effect on ETW.

RESUMO O concreto é o material de construção mais utilizado e nos últimos anos, estudos têm sido desenvolvidos em busca de materiais com desempenho mecânico e durabilidade superior. Com a finalidade de abranger a realidade das obras civis no que se refere à produção in loco do concreto convencional e de alta resistência, diversos métodos de dosagem são propostos. Apesar de esses métodos permitirem obter a proporção ideal entre os materiais constituintes da mistura de concreto, é possível otimizar a composição aplicando-se o conceito de empacotamento de partículas. Diante disso, o presente estudo tem por objetivo avaliar a eficiência do empacotamento de partículas de misturas de concretos de cimento Portland amplamente utilizados na prática da construção civil, obtidas por métodos de dosagem tradicionais. Para isso, foram produzidos três traços deconcreto utilizando o método de dosagem tradicional IPT/EPUSP, sendo dois para concretos com classe de resistência convencional e um de alta resistência. Conhecendo a proporção e a distribuição granulométrica dos materiais constituintes desses concretos, o coeficiente de distribuição de cada mistura foi determinado considerando o modelo de empacotamento de Alfred. Posteriormente, mantendo-se o mesmo coeficiente de distribuição, as misturas de concretos foram otimizadas aplicando o conceito de empacotamento de partículas, sendo determinadas as propriedades físicas e mecânicas dos concretos. No processo de otimização, verificouse lacunas entre as distribuições granulométricas dos materiais constituintes normalmente considerados na produção dos concretos, caracterizando uma deficiência quanto ao empacotamento. Com relação as propriedades do concreto no estado endurecido, as misturas otimizadas apresentaram, em geral, propriedades físicas e mecânicas superiores aos concretos de referência.

ABSTRACT Concrete is the most widely used building material and, recently, studies have been developed in pursuit of materials with superior mechanical performance and durability. In order to cover the reality of the civil works regarding the on-site production of conventional and high strength concrete, several mix design methods are proposed. Although these methods allow obtaining the ideal proportion between the constituent materials of the mixture, it is possible to optimize the composition by applying the concept of particle packing. Therefore, this paper aims to measure the efficiency of the particle packing of Portland cement concrete mixtures widely used in civil construction´s practice, obtained by traditional mix design methods. For this, three concrete mixtures were produced using the traditional IPT/EPUSP mix design method, being two of conventional strength and one of high strength. By knowing the proportion and particle size distribution of the constituent materials of these concretes, the distribution´s coefficient of each mixture was determined considering Alfred´s particle packing model. Thereafter, maintaining the same distribution coefficient, the concrete mixtures were optimized by applying the particle packing concept, determining the physical and mechanical properties of the concrete. During the optimization process, there were gaps between the particle size distributions of the component materials normally considered in the production of concretes, characterizing a lack in packaging. Regarding the properties of the hardened concrete, the optimized mix design generally presented superior physical and mechanical properties than the reference concrete.
